Expanded Notation to Standard Form, Mixed Order

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through it independently, since students at this age benefit more from productive struggle than from being walked through each step, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These expanded to standard form worksheets work well as daily practice, homework, or a focused review activity.

Add 10 sets of expanded notation parts given out of order and write each number, with 0 in missing places. Expanded notation shows each digit times its place value. The parts can be in any order, and a place that is not shown has the digit 0. The directions on the page read: Find the value of each part. Then, add the parts by place value and write the whole number in the box. An answer key is included.

Yes, both. We made it for 4th Grade place value & rounding, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with expanded to standard form. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Find the value of each part and line them up by place. (9 x 10) + (6 x 1,000) + (9 x 1) + (1 x 100,000) + (1 x 10,000) is 100,000 + 10,000 + 6,000 + 90 + 9 = 116,099.

A place that is not shown has the digit 0. (1 x 10,000) + (2 x 10) + (3 x 1,000) + (9 x 1) + (4 x 100,000) has no hundreds part, so the number is 413,029.

Yes. Both sheets have an answer key.
